UK Student Visa Requirements 2026: Documents, Funds & CAS Explained

Introduction

Every year, thousands of international students face UK student visa refusals, delays, or correction requests. In many cases, the problem is not dishonesty or lack of qualifications. Instead, applicants often misunderstand important requirements. A missing document, a bank statement with the wrong closing date, or even a small CAS error can quickly place a student’s dream of studying at a British university on hold.

That ends today. This guide to UK student visa requirements 2026 is the most thorough, plain-English breakdown of everything the Home Office needs from you, including every document on the checklist, the financial proof rules that trip up even well-prepared applicants, and a full explanation of what the CAS actually is and how to get it right. Whether you are applying for the first time from your home country, switching visa routes inside the UK, or extending an existing student visa, this guide gives you the clarity and confidence to get it done correctly the first time.

1. Overview of the UK student visa 2026 requirements framework

The UK student visa, formally called the Student Route, operates on a points-based immigration system. To be approved, you must score 70 points across three measurable criteria:

50 points are awarded for holding a valid Confirmation of Acceptance for Studies (CAS) from a licensed sponsor. 10 points are awarded for meeting the financial requirement. 10 points are awarded for meeting the English language requirement.

Every document you submit, every financial statement you provide, and every English language certificate you attach serves one of these three scoring areas. When you understand that structure, the entire application process becomes far less overwhelming.

The critical insight for 2026 applicants is this: you do not just need to meet these requirements in theory. You need to prove each one through specific, correctly formatted documentary evidence. Caseworkers at UK Visas and Immigration do not assume anything in your favour. They verify what you can demonstrate on paper.

2. What is a CAS and why is it the foundation of your entire application

Before anything else can happen, you need a CAS. Full stop. The Confirmation of Acceptance for Studies is a reference number issued by UK educational institutions licensed as sponsors under the Student visa route. It confirms that an international student has been offered a place on an eligible course and that the institution will act as their visa sponsor.

Your CAS is not a physical document. It is an electronic record of the offer of a place on a course, together with your biographical and other details, as evidenced by a unique reference number.

Think of it this way. The CAS is your university saying to the UK government: “We have accepted this student onto a genuine, accredited course. We are willing to sponsor their visa. We vouch for them.” Without that digital declaration from a licensed institution, your visa application cannot proceed.

2.1 What information does a CAS contain?

Your CAS contains significantly more than just a reference number. It is a virtual document that contains information about your course of study and personal details. Specifically, a CAS includes:

• Your full name exactly as it appears on your passport
• Your date of birth and nationality
• The name and licence number of your sponsoring institution
• Your course title, level, and qualification type
• The course start date and expected end date
• Your total tuition fee for the course
• Any tuition fee amounts already paid and recorded by the university
• Your CAS reference number, which is a unique 14-digit alphanumeric identifier
• Details of any English language test results the university has assessed
• The academic qualifications used to make you an offer

Any mismatch between your application and CAS details can create delays or refusals. Accuracy matters enormously.

Before you use your CAS to apply, read every single piece of information on it carefully. If your name is spelled differently from your passport, if your course start date is wrong, if your tuition fee figure does not match what you have been told, contact your institution’s visa compliance or admissions team immediately and ask for a correction. Do not proceed with a CAS that contains errors.

2.2 How to get your CAS from a UK university

You should request a CAS as soon as you have accepted an unconditional offer, as long as the admissions team have checked all required documents.

The process varies slightly between institutions, but the general pathway looks like this:

• Receive an unconditional offer from a licensed UK university or college
• Accept the offer formally through the institution’s online portal
• Pay any required acceptance deposit (institutions set their own deposit amounts)
• Complete any pre-CAS registration requirements set by the institution
• Submit the required documents to the institution’s visa compliance team
• The institution processes your CAS request and issues your unique CAS reference number by email

Most universities will issue your CAS about three months before you start your degree programme. However, you can usually apply for your CAS up to six months in advance.

2.3 CAS validity: the six-month rule you must not ignore

Your CAS is only valid for six months, so timing is important. Once your institution issues your CAS, the clock starts. You must submit your student visa application before that six-month window expires.

If your CAS expires before you apply, you will need to request a new one from your institution. This creates delays and can push back your course start date. Apply as soon as your CAS is issued and your financial evidence is in order.

2.4 What happens if your CAS has an error

In case of a visa refusal and reapplication, you will typically need a new CAS number. Similarly, if you notice mistakes after your CAS has been issued, contact your institution immediately. All information submitted to the Home Office must exactly match the details shown on your passport and supporting documents. Any discrepancies may result in your student visa application being refused.

3. Full UK student visa document checklist 2026

Here is the complete document checklist for a UK student visa application in 2026. The exact documents required depend on your circumstances, but the core requirements apply to virtually all applicants.

3.1 Core mandatory documents (required for all applicants)

Valid passport or travel document

Your passport must be valid at the time of your application and upon your arrival in the UK. It needs at least one blank page. If your passport will expire before your course ends, it is strongly advisable to renew it before applying. Your passport only needs to be in date at the time the CAS is issued and when you first arrive in the UK, but having an expiring passport in the middle of your studies creates complications.

CAS reference number

Students must enter the 14-digit CAS reference number in their visa application form. This connects your application to your university’s sponsorship record in the UKVI system. You cannot proceed without it.

English language test certificate

You must provide an approved Secure English Language Test (SELT) result from a UKVI-approved provider demonstrating the required English language proficiency level. In 2026, most degree-level applicants need to demonstrate CEFR Level B2 across all four language skills: reading, writing, speaking, and listening. Accepted tests include IELTS Academic UKVI, IELTS for UKVI, PTE Academic UKVI, and Cambridge C1 Advanced for UKVI.

Financial evidence

Proof that you have the required funds to cover your tuition fees and living costs. The specific requirements for financial evidence are explained in full detail in Section 4 of this guide.

Recent passport-sized photographs

Two identical photographs meeting UKVI specifications: 45mm by 35mm, plain white or cream background, clear, unobscured face, taken within the last six months.

4. UK student visa financial requirements 2026: the complete breakdown

The financial requirements section of the UK student visa application is where the majority of refusals occur. Getting this right is not just about having enough money. It is about having the right money, in the right accounts, for the right length of time, evidenced in the right format.

4.1 How much money do you need to show?

The total amount you must demonstrate is calculated by adding two figures together:

Component one: Outstanding tuition fees

The first year’s tuition fee minus any amounts already paid and recorded on your CAS. If your university has recorded a scholarship or fee payment on your CAS, this reduces the amount you need to show. For example, if your tuition fee is £20,000 and your CAS shows £15,000 has been paid, you only need to show £5,000 in outstanding fees plus the maintenance amount. Always check your CAS carefully to confirm what has been recorded.

Component two: Monthly maintenance allowance

For 2026, students must show maintenance funds of £1,529 per month for studying in London, which amounts to £13,761 for nine months, or £1,171 per month for studying outside London, which amounts to £10,539 for nine months.

These amounts are fixed by the UK Home Office and must be strictly followed.

To calculate your total required fund: add your outstanding tuition fee from the CAS to your nine-month maintenance allowance based on your study location. That total is the minimum sum you must demonstrate you hold.

4.2 The 28-day rule: the single most misunderstood financial requirement

Understanding the 28-day rule is non-negotiable. This is the rule that most directly causes otherwise eligible applicants to have their applications refused.

The 28-day rule requires applicants to maintain the minimum required balance in their bank account for 28 consecutive days. The final day of this 28-day period must fall within 31 days of your visa application submission date. Your bank statement must clearly show this continuous balance without any dips below the required amount, even momentarily.

Read that again carefully. Not 28 days before. Not roughly 28 days. Exactly 28 consecutive days, with the final day of that period falling within 31 days before your application date. And the balance must not drop below the required minimum even once during those 28 days.

A hidden financial proof that UK caseworkers check is whether your balance dips below the requirement during the 28-day period. The result is automatic refusal, even if you had sufficient funds for 27 out of 28 days.

Pro tip: keep a buffer of £1,000 to £2,000 above the minimum to account for bank charges, currency fluctuations, or accidental withdrawals.

4.3 Acceptable sources of financial evidence

Not every type of financial evidence is accepted. UKVI has specific rules about what counts.

Personal bank statements: The most common and straightforward option. Statements must clearly show your name, account number, the financial institution’s name, and a continuous 28-day transaction history ending within 31 days of your application date.

Parental bank statements: You can use funds from your parents’ accounts. When using a parent’s funds, you must also provide a consent letter. The consent letter must state the parent’s full name, your name, the relationship between you, a clear statement that they consent to you using the funds for your UK studies, and the specific amount they are providing. You must also provide supporting identity documents for the parent.

Official sponsorship letter: If you hold a scholarship from an approved sponsor body such as a national government, the British Council, or your institution, you will need an official letter on headed paper confirming the full amount and duration of the funding.

Student loans from government-backed schemes: Loans from recognised government or government-backed loan schemes are accepted as financial evidence.

If you use financial sponsorship, the sponsor must be an approved body. This includes the UK government, your home government, the British Council, or a recognised university.

4.4 What financial evidence is not accepted

UKVI does not accept the following as standalone financial evidence:

• Informal loans from relatives or friends without official documentation
• Property valuations or asset statements
• Salary slips without corresponding bank statements showing the actual receipt of funds
• Investment account balances that are not immediately accessible
• Pension accounts
• Credit card statements or overdraft facilities
• Cryptocurrency holdings

4.5 Differential evidence countries: are you exempt from financial evidence?

Even if exempt, it is advisable to maintain proof of funds in case you are called for a UK Student visa credibility interview or random verification check.

Students from certain low-risk countries, sometimes called differential evidence countries, may be exempt from submitting financial documentation as part of their online application. However, this is not a guarantee that you will not be asked to provide it. Always have your financial evidence prepared regardless.

5. English language requirements for the UK student visa 2026

Meeting the English language requirement is the third pillar of your 70-point eligibility score. Getting this wrong, whether by submitting an unapproved test, an expired certificate, or a score below the required threshold, results in immediate refusal.

5.1 The required English proficiency level

For degree-level courses and above, UKVI requires demonstration of CEFR Level B2 proficiency. This means a genuine ability to understand and communicate in complex, academic English across all four skill areas.

For pre-sessional English language programmes and some below-degree-level courses, B1 level may be accepted. Always confirm the exact requirement for your specific course with your institution.

5.2 Approved English language tests for the UK student visa

All English language tests must be from a UKVI-approved Secure English Language Test provider. The most widely accepted options are:

• IELTS Academic UKVI (note: the standard IELTS Academic is not always accepted for visa purposes; you need the UKVI-specific version)
• IELTS for UKVI (also known as IELTS UKVI)
• Pearson PTE Academic UKVI
• Cambridge B2 First, C1 Advanced, or C2 Proficiency (when taken for UKVI purposes)
• Trinity College London GESE and ISE qualifications (for some course types)

For IELTS Academic UKVI, the typical minimum score for degree-level study is an overall band score of 6.0 to 6.5, with no individual skill falling below 5.5 to 6.0, though this varies by institution and course.

5.3 Exemptions from the English language test

Certain applicants are exempt from providing an approved SELT. You may be exempt if:

• You are a national of a majority English-speaking country as designated by UKVI (including the United States, Canada, Australia, New Zealand, and others)
• You have previously completed a degree taught and examined entirely in English within the last five years
• Your university has conducted its own internal English proficiency assessment and is satisfied you meet the requirement
• You are exempt based on the specific terms of your institution’s sponsor licence

Always confirm your exemption status directly with your institution and never assume you are exempt without verification.

6. Photograph requirements for the UK student visa

Your photographs must meet exact UKVI specifications. Submitting non-compliant photographs is a simple but common reason for administrative delays.

Your photographs must be:

• 45mm by 35mm in size
• Taken against a plain cream or white background with no shadows
• Clearly in focus with no red-eye
• Showing your full face without obstruction (no hats, caps, or items covering your face unless worn for religious reasons)
• Showing your eyes clearly, open, and looking directly at the camera
• Taken within the last six months
• Printed on high-quality photographic paper if submitting physical copies

Wear your everyday clothes. Do not wear glasses in your photographs unless medically prescribed and you wear them at all times.

7. UK student visa application process: how your documents come together

Understanding how the documents fit into the actual application process helps you sequence your preparation correctly and avoid submitting before you are ready.

7.1 The correct order of preparation

Stage one: Receive your unconditional offer and request your CAS. Do not begin financial preparation until you know the exact tuition fee figure on your CAS, as this directly affects how much you need to demonstrate in your bank account.

Stage two: Calculate your total financial requirement precisely. Add your outstanding tuition fee (as shown on the CAS) to your nine-month maintenance allowance. Ensure these combined funds are in your bank account and leave them untouched.

Stage three: Begin the 28-day holding period. Start the clock deliberately. Do not let the funds dip for any reason. Set calendar reminders. This stage requires active management.

Stage four: Book and sit your English language test if required. Obtain your results and confirm they meet the required level for your course.

Stage five: Gather all supporting documents including your passport, photographs, TB certificate (if applicable), ATAS certificate (if required), and any consent or sponsorship letters.

Stage six: Complete the online application at gov.uk/student-visa. Enter your CAS reference number carefully. Pay the visa fee and the Immigration Health Surcharge.

Stage seven: Book and attend your biometrics appointment at a UK Visa Application Centre. Upload or submit your documents as required.

Stage eight: Await the decision, set up your UKVI eVisa account upon approval, and plan your travel.

7.2 How UKVI uses your documents to assess your application

When a caseworker reviews your application, they are checking five things simultaneously:

Inconsistency is the silent killer of otherwise strong applications. If your name appears differently on your passport versus your bank statements versus your English test certificate, address it proactively with a supporting letter of explanation before submitting.

8. Credibility interviews: what they are and how to prepare

UK Visas and Immigration often conduct their own credibility interviews for Student Visa applicants before granting a Student Visa. The purpose of the UKVI credibility interview is to ensure that an applicant has a genuine intention to study in the UK.

UKVI credibility interviews are conducted in English. UKVI credibility questions will focus on your reasons for studying in the UK, your background, study and career plans, finances, and your plans after completing your studies.

Not every applicant is called for a credibility interview, but you should prepare for the possibility. To perform well:

Be clear and specific about why you chose your particular course and university. Be able to explain your previous academic background and how it connects to your chosen programme. Know the basic details of your university: its location, its reputation, and why it suits your goals. Be honest and consistent. Your interview answers must align with your written application.

9. Common UK student visa refusal reasons and how to avoid them

These are the most frequently occurring reasons for UK student visa refusals in 2026 and what you can do about each one:

Financial evidence errors: The most common refusal trigger. Bank statements ending too early, funds that dipped below the required amount during the 28-day period, insufficient total funds calculated without correctly accounting for outstanding tuition fees, or missing parental consent letters when using a parent’s account. Fix: calculate your exact requirement, manage the 28-day window deliberately, and use a buffer above the minimum.

CAS errors or inconsistencies: A mismatch between the details on your CAS and your application form. Fix: read your CAS line by line before applying. If anything is wrong, contact your institution before submitting.

Here is your improved version with shorter sentences, clearer structure, stronger flow, and more active voice:

Expired or invalid English language certificate:
Many English language test results stay valid for only two years. An expired certificate or one from an unapproved provider has no value. Fix: Check the expiry date and confirm that your test appears on the UKVI-approved list.

Missing TB test certificate:
Applicants from listed countries must include a TB test certificate. Without it, UKVI will refuse the application. Fix: Check the official UKVI list and complete your test at an approved clinic well in advance.

Credibility concerns:
The Home Office may doubt your genuine intention to study. This often happens when you switch to an unrelated or lower-level course, have a complex visa history, or give inconsistent answers during a credibility interview. Fix: Stay honest, stay consistent, and clearly explain your academic choices.

Non-English documents without certified translations:
UKVI does not accept documents in other languages unless they include certified translations. Fix: Arrange certified translations for all non-English documents before you apply.

10. Extending your UK student visa: what the document requirements look like the second time

If you need to extend your student visa within the UK, whether to complete your current degree, progress to a higher level of study, or resit examinations, the document requirements are broadly similar but with some important differences.

If you are continuing your studies, for example progressing from a bachelor’s to a master’s degree, you can extend your Student Visa. Your new institution must issue a new CAS and you must apply before your current visa expires.

The earliest you can apply for an extension of your UK student visa is three months before the start of your course and before your current student visa expires.

You will generally also need to demonstrate that your new course represents academic progression from your current one. The main exception to this requirement is if you are resitting exams, completing a placement year, or finishing a postgraduate programme you started under a previous student visa.

11. Financial planning: total cost of the UK student visa in 2026

Understanding all the costs involved before you apply helps you plan your budget accurately and avoids the panic of discovering additional charges mid-process.

Here is a full cost breakdown for a student applying for a three-year undergraduate course from outside the UK from April 2026 onwards:

• Student visa application fee: £558 (as of April 8, 2026)
• Immigration Health Surcharge at £776 per year for approximately three years and four months: approximately £2,584
• IELTS Academic UKVI or PTE UKVI test: approximately £220 to £260 depending on country
• Tuberculosis test certificate (if required): approximately £60 to £100
• Biometrics and document handling at the Visa Application Centre: approximately £50 to £100
• Certified translation of non-English documents (if applicable): approximately £50 to £150 depending on volume

The total pre-arrival visa cost therefore sits between approximately £3,500 and £3,600, entirely separate from tuition fees and living costs.

Optional priority processing adds £500, and super priority processing (decision by next working day after biometrics) adds £1,000.

Conclusion

The UK student visa requirements in 2026 are detailed, specific, and unforgiving of careless mistakes. But they are not impossible. They follow a logical structure: earn your 70 points by getting your CAS right, proving your finances correctly, and demonstrating your English language ability through an approved test. Every document on the checklist exists to support one of those three requirements.

The students who get their applications refused are rarely unqualified. They are typically applicants who rushed the financial evidence preparation, submitted documents with small errors, or did not understand the precision the 28-day rule demands. The students who sail through are those who treat the documentation process with the same dedication they gave to earning their university offer in the first place.

You have already done the hard part by winning your place at a UK institution. Give your visa application the same effort, prepare your documents carefully, understand exactly what your CAS contains and how it connects to your financial requirements, and you will be sitting in that British lecture hall sooner than you think.

Top 10 frequently asked questions about UK student visa requirements 2026

Q1. What documents are required for a UK student visa in 2026?

The core required documents for a UK student visa in 2026 are a valid passport with at least one blank page, your CAS reference number from a licensed UK institution, evidence of sufficient financial funds meeting the 28-day holding rule, an approved English language test certificate at CEFR B2 level or above, and recent passport-sized photographs meeting UKVI specifications. Depending on your circumstances, you may also need a tuberculosis test certificate, an ATAS clearance certificate, a parental consent letter if aged 16 or 17, a sponsorship letter, or certified translations of any non-English documents.

Q2. What is a CAS number and how do I get one for a UK student visa?

A CAS (Confirmation of Acceptance for Studies) is a unique 14-digit electronic reference number issued by your UK university or college. It confirms to UKVI that your institution has accepted you onto an eligible course and agrees to sponsor your student visa.
You receive your CAS after accepting an unconditional offer and completing your institution’s pre-CAS registration process, which typically includes paying an acceptance deposit. Your institution emails your CAS reference number and a CAS statement containing your full course and fee details, which you then enter into your online visa application.

Q3. How much money do I need in my bank account for a UK student visa in 2026?

You need to show an amount equal to your outstanding tuition fee for the first year (as listed on your CAS) plus your monthly maintenance allowance for up to nine months. The maintenance allowance for 2026 is £1,529 per month if you are studying in London, totalling £13,761 for nine months, or £1,171 per month outside London, totalling £10,539 for nine months.You must keep these funds in your bank account continuously for 28 consecutive days. In addition, the statement period must end no more than 31 days before you submit your visa application.

Q4. What is the 28-day rule for a UK student visa?

The 28-day rule requires you to hold your total required funds continuously in an accessible bank account for 28 uninterrupted consecutive days. The final day of that 28-day period must fall within 31 days of the date you submit your visa application. The balance must not drop below the required minimum even once during those 28 days. Even a single-day dip below the requirement, regardless of how briefly it occurred, is treated as a failure to meet the financial requirement and results in refusal.

Q5. Can I use my parents’ money for UK student visa financial evidence?

Yes, you can use your parents’ funds as financial evidence for a UK student visa. However, you must provide your parent’s bank statements covering the full 28-day holding period, a signed parental consent letter confirming their full name, your name, your relationship, their consent for you to use the funds for UK study, and the amount they are providing. You must also provide proof of your relationship to the parent, such as your birth certificate, and a copy of their identification documents.

Q6. Do I need IELTS for a UK student visa in 2026?

Most UK student visa applicants need an approved Secure English Language Test result, but IELTS is not the only accepted option. Students can also use PTE Academic UKVI, Cambridge B2 First or C1 Advanced for UKVI purposes, and certain Trinity College London qualifications.

Some applicants may qualify for an exemption. For example, your country may officially use English, your university may have taught your degree entirely in English, or your institution may assess your language ability directly.

Always confirm the exact English language requirement with your university. In addition, make sure you choose the UKVI-approved version of any test you take.

Q7. How long is a CAS valid for a UK student visa?

A CAS remains valid for six months from the date your university issues it. You must submit your student visa application within this period. If the CAS expires before you apply, your institution will need to issue a new CAS number.

This can restart parts of the process and may significantly delay your application. Therefore, apply for your visa as soon as your CAS and financial documents are ready.

Q8. What happens if there is an error on my CAS?

If you notice an error on your CAS, such as a misspelled name, incorrect course dates, or a wrong tuition fee figure, you must contact your institution’s visa compliance or admissions team immediately before submitting your application. Do not apply with a CAS that contains errors. Any discrepancy between your CAS details and your application form or passport can cause delays or result in a refusal. In the event of a refusal, you will typically need a new CAS issued before you can reapply.

Q9. What is an ATAS certificate and do I need one for my UK student visa?

Q10. What are the most common reasons for UK student visa refusal in 2026?
